Attention deficit hyperactivity disorder (ADHD) is one of the most common childhood disorders and can continue through adolescence and adulthood.

One subtype of ADHD is called predominantly inattentive ADHD. Children with this subtype are less likely to act out or have difficulties getting along with other children. They may sit quietly, but they’re not paying attention to what they are doing.

A child with predominantly inattentive ADHD may be overlooked, and parents and teachers may not notice that he or she has any signs of the disorder.

Children with symptoms of inattention may:

Be easily distracted, miss details, forget things, and frequently switch from one activity to another.

Have difficulty focusing on one thing.

Become bored with a task after only a few minutes, unless they are doing something enjoyable.

Have difficulty focusing attention on organizing and completing a task or learning something new.
